<p>PURPOSE:To obtain a method that can prevent blocking when stacking containers up, or after the containers are stacked up, and to obtain containers made up by employing such method. CONSTITUTION:Vertical projections 8 are provided to positions where patterns that are different from each other in a container in the inner layer and a container in the outer layer are brought into contact for the firs time. When one container is put over another container, the containers are turned to right and left in swinging each other, and are stacked up with their parts in the same shape placed on the same position. Thereby, blocking can be prevented when the containers are stacked up. At the same time, horizontal projections 9 are provided on the boundary lines 7 or to the locations near the boundary lines 7, or to the surfaces of petallike patterns, and turning of the containers can be stopped by contacting with such horizontal projections 9. Thereby, blocking can also be prevented.</p> |
